====================
net: sparx5: add support for lan969x switch device

== Description:

This series is the second of a multi-part series, that prepares and adds
support for the new lan969x switch driver.

The upstreaming efforts is split into multiple series (might change a
bit as we go along):

        1) Prepare the Sparx5 driver for lan969x (merged)

    --> 2) add support lan969x (same basic features as Sparx5
           provides excl. FDMA and VCAP).

        3) Add support for lan969x VCAP, FDMA and RGMII

== Lan969x in short:

The lan969x Ethernet switch family [1] provides a rich set of
switching features and port configurations (up to 30 ports) from 10Mbps
to 10Gbps, with support for RGMII, SGMII, QSGMII, USGMII, and USXGMII,
ideal for industrial & process automation infrastructure applications,
transport, grid automation, power substation automation, and ring &
intra-ring topologies. The LAN969x family is hardware and software
compatible and scalable supporting 46Gbps to 102Gbps switch bandwidths.

== Preparing Sparx5 for lan969x:

The main preparation work for lan969x has already been merged [1].

After this series is applied, lan969x will have the same functionality
as Sparx5, except for VCAP and FDMA support. QoS features that requires
the VCAP (e.g. PSFP, port mirroring) will obviously not work until VCAP
support is added later.

== Patch breakdown:

Patch kernel-patches#1-kernel-patches#4  do some preparation work for lan969x

Patch kernel-patches#5     adds new registers required by lan969x

Patch kernel-patches#6     adds initial match data for all lan969x targets

Patch kernel-patches#7     defines the lan969x register differences

Patch kernel-patches#8     adds lan969x constants to match data

Patch kernel-patches#9     adds some lan969x ops in bulk

Patch kernel-patches#10    adds PTP function to ops

Patch kernel-patches#11    adds lan969x_calendar.c for calculating the calendar

Patch kernel-patches#12    makes additional use of the is_sparx5() macro to branch out
             in certain places.

Patch kernel-patches#13    documents lan969x in the dt-bindings

Patch kernel-patches#14    adds lan969x compatible string to sparx5 driver

Patch kernel-patches#15    introduces new concept of per-target features
